MAP16: Blood Keep (Doom 64)

MAP16: Blood Keep is the sixteenth map of Doom 64, designed by Randy Estrella. It uses the music track "Warped Hive", also heard in MAP02: The Terraformer. The level itself is exploring a huge keep and fighting large waves of monsters and tricky puzzles and finding the exit.

Official

 * 1) Right after entering the blue key door and dispatching all enemies behind it, turn right and activate a yellow pentagram wall to raise the pillars blocking the secret. Instead of going up the stairs, activate the bookcase beside it and ride on top of it, and keep edging right to enter the secret cache containing a plasma rifle.

Non-official

 * 1) From the official secret, take the stairs. Open the door closest to the dead end with the bookshelf and take out any enemies inside the room. Another secret cache is right across the door you just entered, simple activate the bookshelf facing the door to reveal a cache containing a few box of rockets and an energy cell pack.

Trivia
The name of this level reoccurs in the lore of Doom (2016), where it is said by the Lord of Hell that the Doom Slayer sought prey in the "tombs of the Blood Keep," whence the priests of its temples brought them down upon him, trapping him and enabling the demons to imprison him in the sarcophagus later kept in the Kadingir Sanctum. Accordingly, the map which follows this level,, is seemingly equated with Kadingir via the designs of its final arena.
